I wonder how many calories/W you need to burn to keep it running and to how much food/hour that leads

That’s a good point, you would probably eat your savings.

Typing while biking. That sounds like an interesting challenge, hehe.

Very true! Maybe you’d burn a few extra calories in the process of typing while biking?

I’m not sure about a laptop or an excercise bike because I own neither, but it would be good if I could stick something on my bike to charge a battery which would allow me to charge my MP3 player, phone or headphones when I’m out and about. I’ve seen backpacks with solar pannels for this purpose but I’m uncertain how well that would work over here.

I’m actually surprised that there isn’t some sort of add-on for the iPod that will do that. It almost seems like a natural way to charge an MP3 player, but I guess the batteries last long enough that it makes this unnecessary.

I can’t imagine just trying to focus your eyes on the screen.
